yApplication filed March 30, r1923. Serial No. 628,726.

To all' 'whom it may concern:

Be it known that I, VALTR ERNEST GUN- NnRsoN,.a citizen of theUnitedStates, residing at Milton, in the county of Rock and State of'Wisconsim have invented certain new and useful Improvements inAdapters, ofwhich the following is a specification. This inventionrelates to adapters.y It will be explained as applied to an adapter foruse with therapeutic lamps.

Some of the appliances or applicators used with therapeutielamps inthc/treatment of disease are in the form of rods of quartz and othersuitable materials. Such rod like vapplicators are primarily used todirect and apply the lamps raysl to body cavities. The adapterhereinafterv set. forth is vparticularly adaptedvto attach suchapplicators to therapeutic lamps.

An example of a therapeutic lampl with which the herein-describedadapter may be used is disclosed in United States Patent No. 1,435,193;granted November 14, 1922. One of the objects ot'this invention is toprovide an improved adapter. Y Another object is to provide an adapterwhich will 'readily accommodate a variety of shapes and sizes ofapplicators.

Another object is to provide an adapter particularly adapted to receiveand hold rod shaped applicators. v

Y Another Objectis which is simple, reliable, readily manipulated.

` Other objects and after appear. j v

v"An embodiment of the invention-is illustrated in the accompanyingdrawing, wherein` Fig.- 1 is an .Outline perspective Qf @typicaltherapeutic 'lamp with fan adapterfor application thereto.

Fig. 2 is an enlar of the adapter, an

Fig. 3 is a longitudinal section thereof. Adapter 1 is adapted forattachment to a therapeutic lamp 2 and to hold an applicator 8. Both thelamp and the applicators may take various forms. Ordinarily the 50 lampcomprises a suitable casing or housing, a ray generator, such as amercury vapor tube, within the casing and the necessary electricalconnections and terminals. Often the casing is double walled to permitv55 circulation of a cooling fluid, and then water to provide an adapterinexpensive and advantages will hereined separated perspective employedthe' lamp into cavities of lthe body.

or other fluid connections.v are provided. The applicators often takethe form ofv rods or stemsy of various lengths,l sizes and shapes. vSuchapplicatorsare .ordinarily to direct or conduct'the rays from 60 highlydesirable that a variety of diiferent applicators may be readily appliedto and removed from aA single lamp. i

The applicator has an attaching plate 5 which may be .of substantiallyrflat and circular shape. Plate 5 has a rearwardly projecting annularflangev 6 Awhich may be knurled lto provide a surface whichmay bereadily ygrasped .to apply and/remove theV same from a lamp. Flange 6may have rearwardly projecting locking lugs 7. These lugs .may fit' intocorresponding slots in the lafmp casing o1" .theyimay be adapted Vto fitinto slotsof'a lamp attaching unit or section such as setforth in'FritZ-A. Anderson ap# plication Serial No5-14,217 iiled November 10, 1921." i`Plate 5 has a l A forwardly projecting tubular hub v8 whose bore, whenthe plate isin posi'- tion, aligns witlrthe ray projecting opening 9 ofthe lamp casing. Thev rear portion 10 'of 'hub' 7 is enlarged andeXteriorly threaded. The /forward'reduced portion of hub 7 divided orbifurcated into two vsimilarv segments 11?' by longitudinalv slots 12.Segments 11 are beveled Vorsloped toward their outer or forward lends,and, throughout the bevel,fslots 12 are enlarged to formA jaw recesses1,3. Anannular shoulder 14 marks Y the'k junction of the lreduced andenlarged portions of hub 8.v

" The'bore through lhub 8 is reduced in diameternearfitsi rear Aend toprovide -a -A pair of similar kjaws '16 are interconnected by a small Ushaped biasing and supporting spring 17. The ends of the legs of spring17 are secured in holes in the base surfaces of jaws 16. The yoke 18 ofspring 100 17 is bent at substantially a right angle to the y.plane ofthe legs of the spring so as to form a foot, adapted to restuponshoulders 15. The yoke is curved so as to remain clear or outside of thereduced bore of the hub and not obstruct the passage of the rays. One ofthe jaws V'16 slidably lies in each jaw recess 13 and is supported byspring 17 with its inner end slightly above the back of they recess soas to give suiicient clearance for the movement of the jaws. Jaws 16 aretapered or iared from front to back so that they may be forced togetheras will be hereinafter described.

An internally threaded tubular cap 2O is adapted to screw upon thethreaded rear portion l0 of hub 8. The forward endet the bore of cap 20is trusto-conieal shaped, approximately to correspond to the taper orslope of jaws 16.

The tendency of spring' 17 is to separate jaws 16 but, when cap 2O isscrewed upon hub 8, the interaction of the sloping or tapered surfacesof the jaws and the boreV of the cap provides a wedging action which'forces the jaws together against the bias of spring 17. The jaws arecaused to approach as the cap is turned back so that the clamping actionof the jaws upon an applicator lying therebetween may be varied asdesired. lhencap 2O is screwed outwardly the wedging action decreasesand the bias of spring 17 separates the jaws.

Applicators may be readily applied to the lamp by inserting them betweenthe j aws or' the adapter, where they are in the path of the rays, andthen turning the cap to cause the jaws to clamp. An applicator' isreadily released by turning' the cap of the adapter in the reversedirection.y The clamping races of the jaws may be formed to `meet anyspecial and peculiar condition as to shape ot applicator. It necessary,each'adapt'er may have several sets of jaws and springs assembled intounits which may be interchangeably applied by merely removing the cap.

Having described my invention what 'I claimas new and desire to secureby Letters Patent, is v i l. An adapter for attaching applicators toatherapeutic lamp and comprising, a hollow hub for attachment to the lampand through which the lightmay pass, appli'- cator clamping jawsYadapted to be moved toward: and from each other to clamp and release anapplicator therebetween, resilient means yfor supporting the'jaws on thehub andaifording 'an unobstructed `light pa's- Y sage' to an applicatorheld by thejaws and acting to bias the-jaws apart, and a` capcooperating with the hub and jaws to hold the same together and so` thatmovement of the cap in one direction causes the jaws to approach eachother and movement in the other direction permits the jaws to separate.2. An adapter for attaching applicators toa therapeutic lamp andcomprising, a hollow threaded hub, a pair of relatively movable clampingjaws, a spring for holding and biasing the jaws apart, said spring beingformed so as not to obstruct the passage of light through the bore ofthe hub, and a hollow cap adapted to be threaded upon the hub andacting'upon the jaws to force the same together against the tension ofthe spring.

3. An adapter i'or attaching applicators to a therapeutic lamp andcomprising, a plate for attachment to a lamp and having an openingtherethrough; a tubular eXteriorly threaded hub on the plate, the boreof thehub aligning with the opening inthe plate and having a shouldertherein; a springresting on the shoulder in the bore of the hub; a pairof jaws supported and biased apart by the spring; and a cap threadingupon the hub and acting upon the jaws to force the same together againstthe bias of the spring.

"4. An adapter for attaching applicators to a therapeutic lamp andcomprising, a plate for attachment to a lamp and having an openingtherein for the passage of light; a slotted tubular Vexteriorly threadedhub projecting from the" plate, the bore or the hub aligning Vwith theopening in the plate and having a shoulder therein; a substantially Ushaped'spring whoseY legs lie parallel to the bore of the hub andwhose-base is curved' so asfnot to obstruct the passage of light andformed at an-angle to the legs to` provide a Ytoot tor resting on theshoulder about thebore ot the hub; a pair offcooperating jaws, onecarriedby'each leg of the spring and lying in one of the slots of thehub; and a threaded cap for application tothe huband cooperating withthe rjaws to move the salme'.
